Novel Concept for HEMS Apparatus

AbstractHEMS (Home Energy Management System) is widely recognized as the useful technology for saving energy. On the other hand HEMS is never influenced around common people. The reason is supposed coming from following three points. 1. High initial cost, 2. Location dependence (The present HEMS is mounted into the wall), 3. Personal unconcern for energy saving. Then I introduce the novel concept for HEMS apparatus. The idea is introducing sensor network technology taking place of the conventional wired system. In addition to that, by introducing energy harvesting technology into the power source of sensor network nodes, each node can continue to work without battery or AC power supply cable.In order to examine this new idea, following step by step study procedure is necessary.At first to examine the validity of sensor network HEMS, secondary to estimate consuming energy amount by using sensor network HEMS, thirdly to proof the continuity working sensor network node without battery.Then we’ve described above study procedure in the case of using solar cell in this paper. Still we’ve added future perspective for using many kinds of energy harvesting (thermal, vibration, wireless power transmission)

Shape Memory Wires in R3

We propose a new model describing the dynamics of wire made of shape memory alloys, by combining an elastic curve theory and the Ginzburg-Landau theory. The wire is assumed to be a closed curve and is not to be stretched with deformation. The derived system of nonlinear partial differential equations consists of a thermoelastic system and a geometric evolution equation under the inextensible condition. We also show that the system has dual variation structure as well as a straight material case. The structure implies stability of infinitesimally stable stationary state in the Lyapunov sense

Comparative Studies of Genome-Wide Maps of Nucleosomes between Deletion Mutants of elp3 and hos2 Genes of Saccharomyces cerevisiae

In order to elucidate the influence of histone acetylation upon nucleosomal DNA length and nucleosome position, we compared nucleosome maps of the following three yeast strains; strain BY4741 (control), the elp3 (one of histone acetyltransferase genes) deletion mutant, and the hos2 (one of histone deactylase genes) deletion mutant of Saccharomyces cerevisiae. We sequenced mononucleosomal DNA fragments after treatment with micrococcal nuclease. After mapping the DNA fragments to the genome, we identified the nucleosome positions. We showed that the distributions of the nucleosomal DNA lengths of the control and the hos2 disruptant were similar. On the other hand, the distribution of the nucleosomal DNA lengths of the elp3 disruptant shifted toward shorter than that of the control. It strongly suggests that inhibition of Elp3-induced histone acetylation causes the nucleosomal DNA length reduction. Next, we compared the profiles of nucleosome mapping numbers in gene promoter regions between the control and the disruptant. We detected 24 genes with low conservation level of nucleosome positions in promoters between the control and the elp3 disruptant as well as between the control and the hos2 disruptant. It indicates that both Elp3-induced acetylation and Hos2-induced deacetylation influence the nucleosome positions in the promoters of those 24 genes. Interestingly, in 19 of the 24 genes, the profiles of nucleosome mapping numbers were similar between the two disruptants
